Abstract: PROBLEM TO BE SOLVED: To provide a ceramic member with edges, capable of being produced while reducing chipping, having improved sharpness, and capable of providing extremely improved processing accuracy by constituting the ceramic member of an alumina-based ceramic material containing a specific vol.% or more of alumina-based phase, allowing the member to satisfy a specified relation between the average particle diameter and the fractional toughness value, forming the edge parts on the outer surface of the member, and forming one of them into a sharp edge part. SOLUTION: This ceramic member contains >=20 vol.% alumina-based phase. The average particle diameter d (μm) and the fractional toughness value KC (MPa.m1/2) satisfy the formula KC/(dA)>=3.5 [exponential number A is within the range of (-0.27)-(-0.20)]. One or more edge parts like ridge lines, formed at the crossing positions of two edge-forming surfaces are formed on the outer surface of the member, and one thereof has the edge tip part having <=0.3 mm width, and shown on the cross section when being cut by an arbitrary face orthogonal to the ridge line direction. When the before formula is satisfied, the maximum height of a surface roughness can be regulated so as to be <=50 μm, even if the sharp edge having 0.3 mm width at the tip part is formed.

IPC: B61F5/22
Filed: 1996-06-26
Abstract: PROBLEM TO BE SOLVED: To improve the accuracy in curve position detection by recording the number and direction which cross a threshold value having curve radius calculated by relative rotation displacement and compensating a difference between running of a branch device and running in main track when a railroad vehicle returns to the main track in the case where the railroad vehicle does not run in the main track due to the branch device when it passes a station yard. SOLUTION: A panel signal 7 generated by a speed generator 3 is input in a control device 2, pulse number is added up, and running position is calculated based on the number of revolutions of wheels and a diameter of wheel. Curve radius calculated based on the running position and a detection signal 6 is checked with railroad track data which is recorded in the control device 2 in advance, and the running position is compensated when the corresponding curve exists in the railroad track data. When a railroad vehicle passes a station yard and does not run in main track due to a branch device, the number and direction which cross a threshold value having curve radius are recorded, and a difference between running of the branch device and running in the main track is compensated when the railroad vehicle returns to the main track.

Title: Resistance spot welding method for metallic sheet
Inventor: NAGATA HIROSHI
IPC: B23K11/11
Filed: 1992-07-14
Abstract: PURPOSE:To prevent the generation of crack by forming a joining extending in the thickness direction at, at least one sheet is joined, making resistance spot welding while the surrounding part of the joining hole is pressurized by an electrode when two metallic sheets are resistance spot welded. CONSTITUTION:Aluminum alloy sheets 1 and 2 are pressurized by the upper and lower electrodes 8 and 9. The axial centers of the electrodes 8 and 9 and through holes 3 and 4 as joining holes are coincident and the surrounding parts of the through holes 3 and 4 are pressurized by the electrodes 8 and 9. Then, the joining parts are melted by a applying a welding current 1-1 between both electrodes. Thus, even when a metallic material having a high coefficient of thermal expansion is joined, the amount of strain caused by solidifying shrinkage is small to make the tensile stress generated at the joined part small. Consequently, the generation of crack caused by solidifying shrinkage at the joined parts is prevented, grinding of the surfaces of electrodes is reduced and the welding work efficiency is improved.

Title: Residual ink amount detection device
Inventor: OZAKI MITSUO
IPC: B41J2/175
Filed: 1990-07-18
Abstract: PURPOSE:To detect a residual ink amount in an ink storage vessel by providing a pressure sensor in an ink path of an ink jet recording device and detecting a pressure increase. CONSTITUTION:A residual ink amount detection device 21 consists of a pressure sensor 22 connected to an area between an ink path 3 and a residual ink amount detection control part 23. A variable reactance pressure transducer is, for example, used which is capable of detecting the pressure of liquid such as ink, as a pressure sensor. The liquid level of ink in an ink storage vessel 2 is set lower than the nozzle position of a recording head 1, and the ink is supplied to the recording head 1 by capillary action. If data is recorded, the ink in the vessel 2 decreases increasing the level difference between the nozzle position and the ink level in the vessel. As a result, the inner pressure of the ink path drops, which is in turn, detected by the pressure sensor 22. This detected pressure value is output as voltage signal and is entered in the residual ink amount detection control part 23. An ink shortage is directly detected to prevent the failure to eject ink.
